Elegoo Centauri Carbon vs Elegoo Neptune 4 Plus
Technical comparison · Fused filament fabrication (FFF/FDM)
Choose Elegoo Centauri Carbon if you need an enclosed, compact CoreXY system with multi-color printing support (up to 4 colors). Choose Elegoo Neptune 4 Plus if you require a larger build volume (320 × 320 × 385 mm) and native Klipper firmware on a Cartesian kinematics.

| Software notes | This printer is natively supported by Elegoo Slicer, a slicing software based on Orca Slicer that provides users with pre-configured, carefully optimized profiles designed to maximize both part detail and overall printing speed. Additionally, the machine's operating system is fully compatible with the most popular and community-endorsed third-party slicing software, such as Orca Slicer and Ultimaker Cura. The versatile onboard connectivity options include standard USB ports and a reliable dual-band Wi-Fi module (operating at 2.4 GHz and 5 GHz). This infrastructure enables effortless remote monitoring and comprehensive control of the printing process via its network interface and the built-in chamber camera, greatly streamlining daily workflow management. | The printer operates with Klipper firmware pre-installed on a 64-bit ARM processor, enabling advanced standard features like input shaping and pressure advance. The user interface is managed via a removable capacitive touchscreen and a dedicated web interface (Fluidd or Mainsail) for remote control and monitoring via Wi-Fi or LAN connection. For file preparation, the machine is compatible with major slicers on the market, including Elegoo Cura (bundled by the manufacturer), UltiMaker Cura, PrusaSlicer, and OrcaSlicer. |
The differences that matter
- Build volume and footprint: Neptune 4 Plus offers a larger work area (320 × 320 × 385 mm compared to Centauri Carbon's 256 × 256 × 256 mm), but requires more physical space (53.3 cm wide vs 39.8 cm).
- Kinematics and structure: Centauri Carbon uses CoreXY kinematics with an enclosed chamber, whereas Neptune 4 Plus features an open Cartesian architecture.
- Thermal management: The Centauri Carbon nozzle reaches 320 °C (compared to 300 °C on the Neptune 4 Plus), supported by the insulation of the closed chamber.
- Multi-color printing: Centauri Carbon supports printing up to 4 colors by adding a dedicated accessory, a feature absent on the Neptune 4 Plus (1 color only).
- Firmware and ecosystem: Neptune 4 Plus natively integrates Klipper for advanced web-interface control, while Centauri Carbon relies on an Elegoo Slicer workflow (based on Orca Slicer) and a built-in monitoring camera.
Which one to choose
Choose Centauri Carbon if…
Choose Elegoo Centauri Carbon if you work in constrained spaces (39.8 × 40.4 cm footprint) and need an enclosed chamber to extrude technical materials at temperatures up to 320 °C. It is the recommended option for those planning to expand to multi-color printing (up to 4 filaments) on a CoreXY structure.
Choose Neptune 4 Plus if…
Choose Elegoo Neptune 4 Plus if your main goal is printing large parts using the 385 mm Z-height and 320 × 320 mm area. It is ideal for users who prefer Cartesian architecture and want a pre-installed Klipper system managed via Fluidd or Mainsail web interfaces.
